ORANJESTAD, Aruba – The attorney for two former security guards arrested in the disappearance last month of an Alabama honors student said Tuesday his clients were being investigated for murder and kidnapping.

The men have not been charged in the disappearance of 18-year-old Natalee Holloway and authorities have not said she was a victim of foul play. Earlier in the day, police said they had not ruled out accidental death in the case.

A judge was to determine Wednesday whether authorities have enough evidence to continue to hold the two men, who deny any connection to the high school graduate, said defense lawyer Chris Lejuez.

“They both say that during the time” of the disappearance, “they were not at the (girl’s) hotel and they don’t know this girl,” Lejuez told The Associated Press.

Lejuez said judicial authorities told him of the murder and kidnapping allegations as he met with his clients.

Meanwhile, police and the FBI kept up a search for Holloway, but a lack of any solid leads was hindering progress after nine days, according to several officers. Local officials asked the FBI to bring in dogs trained to search for people.

The parents said they had not received any request for ransom or any other evidence that she had been kidnapped in this Dutch Caribbean territory.

If they are actually going to bring murder charges that have to know something. There must be some form of evidence or a possible confession from one of the suspects. The police had also questioned the three “person’s of interest” as well and who knows what came from those interrogations?
